SUCTION APPARATUS FOR PAPER -MILLS.

SPECIFICATION forming part of Letters Patent No. 478,290,dated July 5,1892. Application filed December 19, 1891- Serial No.'415,5'79. (Nomodel.)

To 00% whom it may concern:

Be it known that we, EPHRAIM $ANDERSON,

and FRANK O. BASE, citizens of the United- States, residing atCleveland, in the county of Ouyahoga and State of Ohio, have inventedcertain new and useful Improvements in Suction Apparatus forPaper-Mills, of which the following, with the accompanying drawings, isa specification.

Our invention relates to apparatus for removing water from pulp and fromthe fiber of paper as it is carried by the wire over the rolls in apaper-mill.

The object of our invention is a mechanism, which is simple inconstruction and efiective in operation, to remove water from pulp andpaper while the same is being carried over the wire; and it consists inthe construction and combination of parts, as shown in the drawings,described herein, and defined in the claims.

In the drawings, Figure 1 is a side elevation in generaloutline,illustrati ng the application of our invention. Fig. 2 is anenlarged vertical section of our device on the line 00 a: of Fig. 1.Fig. 3 is an enlarged elevation of our suction device and the pump. Fig.at isa front end view of the suction device with the face-plate removed.Fig. 5 is an opposite end view of the suction device, showing the pipesthat make connection with the endless series of suction-boxes. Fig. 6 isan outside end view of the suction device and illustrates the outsideface-plate with gear attachment. Fig.

7 is an enlarged broken vertical sectional View illustrating the meansemployed to insureatight closing of the radial holes through therotating shell. Fig. 8 is an enlarged longitudinal section illustratingthe arrangement of the suction-regulator and suctionpipe with referenceto each other. Fig. 9 is an interior view in cross-section of the ringof the rotating shell; and Fig. 10 is an enlarged detail view ofthesuction-boxes, the length of the boxes being contracted withreference to their width.

In the drawings, Fig. 1 shows in outline, in elevation, the wire W andthe rolls R, over which the wire travels. The endless series of boxes Btravel over rolls R. The suctionregulator stands outside of a verticalline with the endless series of boxes, and the suctionregulator pipesextend in between the laps of the endless series of boxes to makeconnection therewith. The-relative location of the invention to the wireand rolls of a paper-mill is illustrated by Figs. 1 and 2.

The suction-boxes B are preferably constructed of rubber and consist ofopen-top boxes the width of the wire W and rolls R and have an openingbin the bottom at their center. The end pieces B consist of encllesspieces of rubber grooved part way through their depth, into whichgrooves fit the partitions B This construction allows the boxes to passeasily over the rolls R by opening'a little as the boxes round therollers, and still they close tightly together when on a straight lineas they are immediately under the wire W.

Inside the end pieces B are adjustable heads 13"", capable of movementlongitudinallyin the boxes. Arod b extends through the boxes, passingthrough the end pieces B" and the movable heads 13". Said rods b have ahead b" upon the outside of the box or have other means provided forturning the same. Within the end pieces B" the rods 1) are smooth; butinside said end pieces the rods are threaded nearly to the middle of therods, one end having a right-hand thread and the opposite end aleft-hand thread. The movable heads 13"" are also threaded interiorly,so that when the rods b are turned the heads B may be thrown to or fromthe .middle of the boxes, and thus adapt them to use when running paperof different widths through the mill. The rolls R, over which theendless series of suction-boxes travel, are such as are in common use inpaper-mills, and need no description.

Our suction -regulator consists of a shell formed of a ring A (throughwhich are radial openings at and nipples a on the periphery of said ringfor making pipe connections therewith) and face-plates A and A". Saidfaceplates are secured to the ring A by means of bolts a", asillustrated. A suction-pipe C, which also serves as an axle for thesuctionregulator shell, passes through the center of said shell, andthe-shell rotates thereon. To make the shell air-tight around saidsuctionpipe 0, we employ suitable stuffing-boxes C. To the face-plate Awe attach a gear A to provide a means of driving the suction-regulatorshell. lVithin said shell is a stationary cylindrical block D.

Below the suction-pipe 0, between it and the cylindrical block D, weinterpose springs E or rubbers to force the said block D tightly againstthe inner face of the ring A of the shell to insure a tight closing ofthe radial openings a. In the top of said block D an opening D is made,preferably wide enough to leave open not more than three of the radialopenings a. An opening 0 is made in the top of the suction-pipe G tocommunicate with the opening D. Said suction-pipe is open through itslength from said opening 0 to the suction-pump P, and it is closedoutside said opening 0 to the opposite direction, as seen at c.

To the nipples a are attached pipes B, which bend over the edge of theshell toward the shaft 0, runalong the shaft 0 to a point under themiddle of the suction-boxes B, and then turn outwardly, so as to makeconnection with the holes I) in said suction-boxes. The radial part B ofthe said pipes is preterably made of rubber, so that they will beyielding and that three of them may be in connection atall times withthe suction-boxes B. Instead of using rubber pipes for this purpose,metal pipes with spring-operated sliding sleeves may be used. Thesepipes 13 must be so arranged as to register with the openings 1) in thebottoms of the boxes B. To keep said pipes B and their radialprojections B in proper position, we use a spider F of any suitableconstruction.

G. G are brackets to support the suctionpipe 0 and thesuction-regulator, and H H are brackets to support the rolls R R.

The wire W, the endless series of boxes, and: the suction-regulator areeach driven by separate power connections.

The operation of our apparatnswill be readily understood from thedrawings and the description already given. The wire XV carries thepaper or pulp over the boxes B, and said boxes travel with said wire. Inthe travel of the boxes B the radial pipes B make connection with theopening I) in the suction-boxes, and the pump P creates a vacuum in theopening D of the suction-regulator, which draws the water from the paperor pulp over the boxes B as they come into connection, and the water iscarried out through the suction-pipe 0. As the shell of thesuction-regulator turns the difierent pipes B are brought to registerwith the boxes B, and the cylindrical block D keeps closed all theradial openings a, except those that are in connection with said boxesB.

The machine will work for different widths of paper by adjusting themovable heads 13" of the boxes B, as hereinbefore described.

Our invention may take on various modifications in details ofconstruction, and we do not therefore limit ourselves to the exact formand arrangement of parts, as shown and described.

That we claim as our invention, and desire to secure by Letters Patent,is.
